Does any one know where ot if I can still get hold of the home brew kits to a beer called Dog Bolter it was originally made by the Firkin chain of pubs it came on draft or alterativly it was made in to a home brew kit.

The Firkin brewing arm ceased in 1999 and the entire Firkin brand was scrapped a couple of years later, so you just ain't going to get Dogbolter any more.
If you want a decent homebrew kit that's associated with a proper brewery and gives consistent results close to what you'd buy in the pub, try any of the Woodforde's kits :http://www.woodfordes.co.uk/html/shop_online.html" onclick="window.open(this.href);return false;
